By default, natbib does not provide a citation command with author-year in parathesis and no comma between author and year. An workaround is to use the citation command with comma and pass the following to the preamble: \setcitestyle{aysep={}} This will remove the comma between author and year globally in the output. If you want the comma to be omitted in the LyX view as well, paste the following to Document > Local Format, hit "Validate" and "OK" (you might need to restart to see the effect): CiteFormat authoryear !open ( !sep ; !close ) !citet %!startlink%%!abbrvauthor%%!endlink% %!open%%!textbefore%%!year%%!nextcitet% !citealt %!startlink%%!abbrvauthor% %!textbefore%%!year%%!endlink%%!nextcitealt% !citealp %!startlink%%!abbrvauthor% %!year%%!endlink%%!nextcitealp% !nextcitet {%next%[[%!close%%!sep% %!citet%]]} !nextcitealt {%next%[[%!sep% %!citealt%]]} !nextcitealp {%next%[[%!sep% %!citealp%]]} cite %!citet%%!textafter%%!close% citep %!open%%!textbefore%%!citealp%%!textafter%%!close% citealp %!textbefore%%!citealp%%!textafter% citeauthor %!startlink%%!abbrvauthor%%!endlink%%!nextauthor%%!textafter% citeyear %!startlink%%!year%%!endlink%%!nextyear%%!textafter% End HTH, Jürgen
